T0 AIJL PERSONS TO WHOM THESE PRESENTS MAY COME:

Be it known that I, PATRICK HUTCHINSON, latevof Chicago, in the StateVof Illinois, but .now of Boston, in

the county of Suffolk, and rState of Massachusetts, have invented anewand useful or improved Churn, and do 'l l hereby declare the same tobe fully described in the following specification, and represented inthe. accompany-` ing drawings, of which` 4 Figure 1 is a frontelevation, and Figure 2 a transverse section of it. p Figure 3 is ahorizontal section of the churn-tub, showing the two dashers thereof.

In such drawings, A denotes the saidltub or vessel for holdingtheereamito be ehurned, it being placed on i a platform, B, and within agal1ows-frame,`0, erected ony 'such platform. Within the churn are twodashers, D. D', `whose rods, a a', extend up through the covert of thetub, andat their upper ends are hinged or jointed' frame C, in manner asrepresented in the drawings. The fulcra c c of the levers project fromthe said frame.A The pendent arms of the said two levers have t'woconneetinglrods, F F', jointed to them. These two rods at their innerends embrace one crank-pin, G, arranged within the slot d of a. slottedcrank, H, and provided with a, clamp-nut and screw, as shown at e, bywhich its position within such slot, or from one to the other endthereof, may bevaried, as circumstances may require. The said crank isxed upon one end of a driving-shaft, I, duly supported in boxes fg, andprovided with a iiy-wheel, 7i, and a era-nk, z'. By laying Vhold of thesai'd crank" gether, and with respect 'tothe l and revolving it,reciprocating vertical motions will be imparted to each of the dasherswithin thcrtub, whereby i the churning of crea-m when in the tub willybe speedily and thoroughly effected. i

"lhe object of having the crank-pn G adjustable along its crank, andproviding it with a clamp-screw and o nut, as described, is to enablethe degree of vertical movements of the dashers to be varied accor iding to the depth of cream which may be within the tub at any one time.It is very desirable that each of the dashers should always riseentirely out ofthe cream during each upward movement of suchmdashe'r,suchbeing in order i i that'airlmay be drawn into4 the cream. After lthecream may have been beaten awhile it b e orlless, or increases in depthin the tub, and were each of the dashers to hav ment, it could notrbemade to rise out of the cream. By having the crank a eachdashermay beincreased, as occasion may require, fromtime-to time,

comes swelled more l e. one constant amountof m0vedjustable, asspecified, the rise of o to cause it to pass out of the cream.

The extent of vertical movement of each dasher will depend on thedistance of the `crank-pin G from theazris of the driving-shaft.

I do not claim'two dashers working in a single tub.V What Iclaim is-l Yf The arrangement and combination of the two bent levers E E', theirconnecting-rods F', single adjust.

able crank-pin G, and slotted crank H, together and witlrthedriving-shaft, the two churn-dashers D D', and the gallows-frame C, thewhole being substantially as specified. i
